Delta Airlines' flight change policy typically allows changes to be made to flights, subject to certain conditions. Here are some key points regarding Delta's typical policy, but keep in mind that specific details may vary based on the ticket type, fare rules, and other factors:

Change Fees: Delta often charges a change fee for altering a flight, unless you have a flexible or unrestricted ticket. The fee amount can vary depending on the fare class and the type of ticket purchased.

Ticket Type: Basic Economy tickets usually have more restrictions and may not be eligible for changes or refunds. Other fare classes like Main Cabin, Delta Comfort+, and Delta One might offer more flexibility.

Change Restrictions: Changes to flights, such as date, time, or destination, are typically allowed within certain limits. However, availability on the desired new flight might affect the change possibilities.

Process for Changes: Changes to Delta flights can often be made online through the Delta website or mobile app. Additionally, you can contact Delta's customer service or visit a Delta ticket office to request changes.

Refunds: Refunds for changed flights might not be available unless the fare rules permit it or if there are specific circumstances covered by Delta's policy.

Flight Protection during Changes: In some cases, if Delta initiates a change to your flight (such as a schedule change), they might offer alternative options or allow you to request a refund.

Elite Status and Membership Programs: Passengers with elite status or who are part of Delta's frequent flyer program might have additional benefits or waived fees for flight changes, depending on their membership level.
